MINUTES

The shareholders of the company Solvay S.A. with its corporate offices in Brussels, rue de Ransbeek, no. 310, gathered virtually for their Ordinary annual meeting on Tuesday, May 11, 2021, at The Event Lounge, Boulevard Général Wahis 16 F 1030 Brussels.

The session was opened at 10:30 am by the chairman N. Boël.

In view of the exceptional situation related to the coronavirus and the measures taken by the authorities restricting gatherings, shareholders will not be able to participate physically in the General Meeting. Shareholders are invited to exercise their rights by voting by proxy or by virtually participating in and voting during the General Meeting.

N. Boël welcomed the shareholders who were participating remotely in this General Meeting. His thoughts were with the people, families, friends and colleagues who have been victims or have suffered the impact of the Covid-19 crisis. He then reviews the three challenges that the Group faced in 2020: the major health crisis, the adaptation of our activities and the management of the Group to this crisis situation and finally the acceleration of the transformation of the Group with the objective of growing its activities in the future.

N. Boël recalled the initiative to create the Solvay Solidarity Fund and the contributions, notably from shareholders, management and employees, which have enabled this fund to provide support to more than 1600 families affected by the pandemic and its consequences.

He then spoke about the financial results and the record cash generation achieved in 2020, the proposed payment of a dividend equal to that of last year (EUR 3.75 gross per share) and commented on the evolution of the share price.

The transformation of the Group has accelerated with the implementation of the GROW strategy, the initiatives taken in the field of ESG (Environmental, Social and Governance) as well as the One Planet programme and its associated objectives.

In terms of governance, the Board's activities and interactions with the senior leadership team have been intensified to ensure that together they identify and implement measures to address the Group's challenges in this period of crisis and monitor the effects on the Group's activities and stakeholders. He also reviews the activity of the Nomination and Compensation Committees.

N. Boël then thanked Evelyn du Monceau and Amparo Moraleda who were leaving the Board at the end of this meeting, both for their major contribution as Board members and also as members of the Nomination and Compensation Committees. He mentioned the candidacies of Edouard Janssen and W. Colberg, who were presented to the meeting to replace the two retiring directors.

N. Boël announced the creation of an ESG Advisory Committee of the Board, chaired by Matti Lievonen.

He concluded by thanking once again CEO Ilham Kadri, the senior management and the staff for their resilience and the results achieved in 2020.

In accordance with article 33 of the by-laws, the Assembly's Office was composed.

The Chairman designated Mr. Michel Defourny, Group Corporate Secretary of the company, as Secretary.

Of the shareholders, Mrs. Savina de Limon Triest and Mrs Sandrine van Zeebroek agreed to act as tellers.

Ms Ilham Kadri in attendance, completed the Assembly's Office.

• 2 -

The Chairman noted that:

• the notifications complete with the agenda were published in the "Moniteur belge," "L'Echo" and "De Tijd" of April 9, 2021, with a specimen copy of each of these publications made available to the tellers;
• the registered shareholders were also notified by letter on April 9, 2021 as were the Directors and the External Auditors on the same date; the model letter is also made available to the tellers.

According to the attendance list signed by present at the meeting, both in their own name as well as proxyholders, the shareholders represented owned a collective total of 66.905.959 shares of the 105.876.416 that make up the registered capital, or 63,19 %.

The Chairman declared the meeting properly constituted.

The shareholders then went on to examine the agenda point by point.

1. The Board of Directors had drawn up a management report on operations for the fiscal year 2020 – including a Declaration of Corporate Governance –, in which may be found all information required by law. The Board took note of the report of the External Auditor and made no particular remarks on its contents.

The Chairman noted that the necessary measures had been taken to meet legal obligations in terms of distribution of the management reports concerning the operations of the fiscal year 2020, including the Declaration of Corporate Governance, and the report of the Auditor.

In light of these circumstances, the meeting opted not to have the management report on the operations of 2020 read.

I Kadri recalled the Group's Vision and the essential role of Chemicals for society, particularly in this period of crisis for Covid-19. This crisis has required radical changes in the way people and teams work, relying heavily on digital technologies. This was also the case in our relationships with our customers and investors at a time when increased interaction was so necessary.

I Kadri went on to describe the solidarity mechanisms implemented by the Group in 2020 (maintaining salaries at 70% during periods of unemployment, creation of the Solvay Solidarity Fund, etc.).

She then reviews the 2020 results of the One Planet objectives, in particular the reduction in GHG emissions above the trajectory defined in the Paris Climate Agreements. These results are the result of twenty-eight projects whose objective is to reduce CO2 emissions by 1.8 M tons within 3 years.

I Kadri then returned to the financial results for 2020 (turnover of 9.0 GEUR, EBITDA of 1.945 MEUR and Free Cash Flow of 963 MEUR). She commented on the highlights, including the EUR 332m cost reduction and the significant write-downs in the second quarter. The Group's debt has been reduced by EUR 1.4bn over the period 2019-2020, and pension liabilities by EUR 0.8bn, resulting in cash pension cost savings of EUR 100m per annum. Based on this situation, the rating agencies have confirmed our investment grade rating.

She went on to describe the most recent steps in the Group's transformation: divestment of low return commodity businesses, accelerating the simplification of the organization to increase agility and efficiency, and intensifying partnerships with our customers.

I Kadri then described the many incentives and innovations leading to sustainable solutions that the Group is currently implementing.

She concludes by commenting on the first quarter 2021 results and full year outlook announced as part of this announcement.

The supporting documents for the speeches by Mr. Nicolas Boël and Mrs Ilham Kadri will be attached to the minutes. They will also be distributed on the Solvay Internet site.

In view of the wide distribution of the Auditor's report, reading of it was dispensed with.

In conformity with regulatory provisions, the annual financial statements, the management report, the Declaration of Corporate Governance, the report of the Auditor, as well as the Compensation Report were submitted to the Works Council of Solvay SA at Brussels.
